GATE | Gate IT 2008 | Question 15
A paging scheme uses a Translation Look-aside Buffer (TLB). A TLB-access takes 10 ns and a main memory access takes 50 ns. What is the effective access time(in ns) if the TLB hit ratio is 90% and there is no page-fault?
Explanation: Effective access time = hit ratio * time during hit + miss ratio * time during miss
TLB time = 10ns,
Memory time = 50ns
Hit Ratio= 90%
E.A.T. = (0.90)*(60)+0.10*110
